Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare the tool read-only, idempotent, open-world, and non-destructive, so the description only adds the source URL and return type. It does not describe the DataFrame's columns or time range, but the annotations cover the key safety and side-effect aspects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very concise, with the resource name and URL front-loaded, and the return type lines are minimal. However, it is fragmented into disconnected pieces (title, URL, return annotation) rather than a cohesive sentence, slightly reducing readability.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with no parameters and strong annotations, the description provides the essential information: the exact index name, source, and return type. It does not specify the structure of the returned DataFrame (e.g., daily values, columns), so an agent may not know exactly what data to expect, but it is sufficient for a basic invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has zero parameters, so there is nothing to explain beyond the absence of inputs. The baseline score of 4 is appropriate because the description adds no misleading parameter information and it clarifies the return type.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies the exact resource: the Jisilu convertible bond equal weight index, and the ':return:' line explicitly states that this tool returns that index. It is differentiated from sibling bond tools by naming the specific index and source, though it lacks an explicit verb like 'get' or 'fetch'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no guidance on when to use this tool compared to alternatives such as bond_cb_jsl or bond_index_general_cbond. There are no exclusions, alternative suggestions, or contextual cues to help an agent decide when this is the right choice.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
